Born in Santa Cruz de Tenerife, Canary Islands, Mascarell joined Real Madrid's youth system at the age of 17, arriving from local CD Laguna de Tenerife. On 21 August 2011 he made his debut as a senior, playing with Real Madrid Castilla against Sporting de Gijón B for the Segunda División B championship; he contributed with 24 games during the season (11 starts) as the B's returned to Segunda División after an absence of five years, scoring twice in the process.
Mascarell started the 2012–13 campaign with the C-team also in the third level, but was promoted back to the reserves after only a couple of weeks. He played his first professional match on 28 October 2012, coming on as a substitute for Pedro Mosquera for the last 17 minutes of a 2–4 home loss against Sporting de Gijón.
On 6 August 2014, Mascarell joined English club Derby County on a season-long loan. He made his debut five days later, as a 53rd-minute substitute for Will Hughes in a 1–0 win against Rotherham United at Pride Park.
He played for Spain at under-20 level. Mascarell has origins in Equatorial Guinea on the paternal side. In May 2012 he was called by the national team of that country for the 2014 FIFA World Cup qualifiers against Tunisia and Sierra Leone. He travelled to Malabo, but nonetheless declined to play in any of the two matches because he had already represented Spain at youth level and did not want to give up on that option; according to the local press, Federación Ecuatoguineana de Fútbol was completing the administrative procedures of his eligibility.
